Abstract

(57) [Summary] [Purpose] The present invention relates to a push button switch device used in the operation panel of various electronic devices, and in particular, the purpose is to provide a thin push button switch device with a good operating feel. It is something to do. [Structure] The protrusion 3b provided on the case 3c and the engagement part 4a of the button 4c are engaged, and when the button 4c is pressed, the button 4c is elastic with the engagement part between the engagement part 4a of the button 4c and the protrusion 3b as a fulcrum. Since the contacts 1a and 1b are brought into contact and separated through the body 6, the button 4c does not need to be guided by the case 3c, and the push button switch device can be made thinner and the operating feel can be improved.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for operation panels of electronic devices and OA (office automation) equipment. The present invention relates to a pushbutton switch device used in an input device or the like.

0002

[Conventional technology]

A conventional pushbutton switch device is illustrated in FIG.

0003 According to the same figure, the pushbutton switch includes a rigid substrate 1 and a pair of opposing substrates on it. Contacts 1a and 1b arranged in parallel, and protrusions arranged above the contacts 1a and 1b. A cup-shaped elastic body 2 having an opening 2a, and a hole 3 provided to match the elastic body 2. It consisted of a case 3 with a hole 3a and a button 4 placed in the hole 3a.

0004 Next, to explain the operation, when the top surface 5 of the button 4 is pressed down, the button 4 will As it moves downward along the hole 3a, the elastic body 2 is compressed and the protrusion 2a is Move downward. When the top surface 5 of the button 4 is further pressed down, the protrusion 2a will eventually come into contact. The contact point 1a and the contact point 1b were electrically connected by pushing down the point 1a.

[0005]

[Problem that the idea aims to solve]

However, in the above conventional pushbutton switch device, the upper surface of the button 4 There is no problem if you push down the center of 5, but if you push down the edge of the top surface 5 , this causes the button 4 to tilt and force is applied to the hole 3a, reducing the operational feel caused by pressing down. In order to prevent this, the length 3b of the hole 3a is increased. In order to reduce the inclination of the button 4, it is necessary to remove the button from the bottom of the board 1. 4. Problem that the height of the entire pushbutton switch device up to the top surface becomes high. was there.

[0006] The present invention solves these conventional problems and provides a good operating feel and The object of the present invention is to provide a pushbutton switch device with a low height.

[0007]

[Means to solve the problem]

In order to solve the above problem, this invention has a protrusion on the button near the hole in the case. The structure includes an engaging portion that engages with the holder.

[0008]

[Effect]

Therefore, according to the present invention, the button engages with the protrusion provided near the hole in the case. By providing an engaging part that rotates, the button rotates about the engaging part as a fulcrum. Since the button moves in the direction, the direction of movement can be determined independently of the hole in the case. This prevents deterioration of the operating feel.

[0009]

【Example】

An embodiment of the pushbutton switch device of the present invention will be described with reference to FIGS. 1 and 2. In addition In the description, parts that are the same as those in the prior art will be given the same numbers. In the same figure According to the invention, a pushbutton switch device includes a rigid substrate 1 and a substrate 1 facing each other on the substrate 1. The contacts 1a and 1b arranged above the contact points 1a and 1b and the protrusion 6a arranged above the contacts 1a and 1b are A cup-shaped elastic body 6 held by the user and a protrusion provided at the end of the hole 3a provided on the elastic body 6. 3b, an engaging portion 4a that engages with the projection 3b, and the elastic body 2. Insert the button 4c with the matching protrusion 4b into the hole 3a of the case 3c. It was established.

0010 Next, to explain the operation of the above embodiment, the upper surface 5a of the button 4 is pressed down. Then, the button 4c moves downward with the engaging part 4a that engages with the protrusion 3b of the case 3c as a fulcrum. , the elastic body 6 is compressed by the protrusion 4b of the button 4c, The protrusion 6a of the elastic body 6 moves downward. Further press down on the top surface 5a of the button 4c. Then, the protrusion 6a eventually pushes down the contact 1a, and as shown in FIG. b is electrically connected.

[0011] As described above, according to the above embodiment, the movement of the button 4c is caused by moving the button 4c through the hole 3 of the case 3c. Since it is not interfered with by Since the information is transmitted to the finger, a push button switch device with a good operating feeling can be obtained. Ma In addition, the hole 3a of the case 3c is simply for storing the button 4c, and is not used conventionally. As shown in the example, since there is no need to increase the length of the hole 3a of the case 3c, Reduce the height of the entire push button switch device from the bottom surface of plate 1 to the top surface of button 4c can do.

0012 In addition, FIG. 3 shows the main part of another embodiment, and the button 4c has a substantially spherical shape. A mating portion 4d is provided, and a protrusion 3d that engages with the engaging portion 4d is provided on the case 3c. The same effects as the embodiment shown in FIG. 1 can be obtained.

[0013]

[Effect of the idea]

As is clear from the above embodiment, the present invention has a button provided near the hole in the case. An engaging part that engages with the protrusion is provided, and a direction in which the button rotates about the engaging part as a fulcrum. This means that even if you press down on the edge of the button, the button will not fit into the hole in the case. Since the movement of the main body is not interfered with, the operation feeling is good, and the length of the hole in the case can be made longer. Since there is no need to do so, the overall height of the pushbutton switch device can be reduced. It is something.
